Nikon Optiphot MicroscopeThe Optiphot was introduced around 1978, inheriting some features from 1976 Metaphot and Biophot,with the same CF optics but more options and some cost reductions, including lower illumination power. Nikon Labophot Microscope #120432 *Power Tested*eBay item number: 294867880389Condition: Used Manufacturer: Nikon Model: 120432 Includes: 1 Labophot microscope Condition: Nikon Labophot Microscope #120432 *Power Tested*. Clean, good condition. Used. This item was previously owned and was working with other working equipment. See photos for exact item, condition, and details on model available. 
Received 9 June 2022Despite being advertised as a Labophot, it is an Optiphot, as embossed on its "Nikon Optiphot" arm plate.Plastic base pads are fine. Those tend to be problematic on Optiphot 2... The lamphouse was thankfully intact, having been removed as requested. Bulb lights; filament shows clearly in the field lens; diffuser is missing... A cheap substitute was ordered from Amazon.  Condenser carrier and rack are intact and working, but neither coarse nor fine stage focus knobs work. Bizarrly, power connecton for 12V bulb uses 110VAC plug and receptacle:  ...although they match those on page 10 of the Optiphot instruction manual. Condenser carrier and rack are seemingly identical to those on the diaphot Optiphot 66; unlike the 66, its stop actually prevents running off its pinion. That carrier design seems odd; an upper U is rigid to the rack, with a screw that anchors condensers to it, but a lower spring-loaded ring with two adjusting screws that center condensers.  Condenser and substage assemblies mount on a dovetail that is removable from the (broken) stage focus rack.  FocusOptiphot-1 (and Labophot) fine focus differs from Optiphot-66: -1 fine focus on the left; -66 fine focus is to the right, with its fine focus shaft Those last (metal) gears' 6 cog sticks thru a large brass spacer/bushing plate to drive a first coarse focus coaxial sun gear, which smaller cog drives the coarse focus planetary gear, which small cog drive the coaxial focus pinion sun gear. This Optiphot-1 focus had been already fiddled; its first coarse focus sun gear was missing, and its large brass planetary gearcase was only loosely threaded onto its coarse focus tube. After tightening, Optiphot coarse focus knobs had about 1mm end play, and grease viscosity fails to resist stage drift; that rack runs in crossed bearings. The -66 coarse focus tube has an improvised retaining nut on the end without gears; its brass planetary gearcase is still tightly threaded to its coarse focus tube. Both focus blocks are the same width, so presumably matching fine focus shaft lengths. See Labophot Fine Focus for gear repair details. CondenserBought a Zeiss 0.9 flip-top condenser; got some advice.Bought a Nikon swing-out condenser; not enough working distance for 3mm epi plate over the stage. ELWD condenser arguably has too much working distance.
